Apple Machintosh SE

The Macintosh SE, introduced in March 1987, was a significant upgrade to the Macintosh Plus, offering improved expandability and performance. It featured an 8 MHz Motorola 68000 processor, 1MB of RAM (expandable to 4MB), and was the first compact Mac to include an internal expansion slot for additional hardware upgrades. The SE also introduced Apple Desktop Bus (ADB) support, allowing for easier peripheral connections, and improved SCSI throughput, doubling the speed of its predecessor. It was available in configurations with dual 800K floppy drives or a 20MB or 40MB hard drive, making it more versatile for professional users. In August 1989, Apple released an updated version with a SuperDrive (FDHD), enabling support for 1.4MB high-density floppy disks. The SE remained popular until it was replaced by the Macintosh Classic in 1990.
